Counts of Dammartin explained

The Counts of Dammartin were the rulers of the county of Dammartin, based in the current commune of Dammartin-en-Goële as early as the 10th century. Located at the central plain of France, the county controlled the roads of Paris to Soissons and Laon. It seems that this county was initially held by Constance, the wife of Manasses Calvus, the first Count. The name Dammartin-en-Goële comes from Domnus Martinus, the Latin name of St. Martin of Tours, who evangelized the region of Goële in the fourth century. A small town in the district of Meaux in the Department of Seine-et-Marne, ancient village of Region of Île-de-France, it appears to go back to the earliest times; Dammartin-en-Goële, also called Velly, was in 1031 one of the most significant places in France.
